' the machine.

Patented Sept. 15, 1936 UNITED STATES QFFIQE 7 Claims.

This invention relates to new and useful improvements in the general art of harvesters and more particularly to a machine especially adapted for harvesting peanuts.

The principal object of the present invention is to provide a machine which will plow up peanut plants and subsequently pick the same up and dump them in an orderly manner.

Another important object of the invention iS to provide a peanut harvesting machine which will save the expense of paying numerous men heretofore required in attending to the harvesting of peanuts.

Another important object of the invention is to provide a machine which in many respects is automatic.

Other important objects and advantages of the invention will become apparent to the reader of the following specification.

In the drawings:

Figure 1 represents a side elevational view of Figure 2 represents a top plan view. of the machine.

Figure 3 is a longitudinal sectional view through the apparatus.

Figure 4 is a transverse section on line 4-4 of Figure 1.

Figure 5 is a side elevational view of one of the pulleys.

Figure 6 is a fragmentary detailed sectional view on line 6-6 of Figure 1.

Figure 7 is a fragmentary detailed sectional view substantially on line 'l-'I of Figure 2.

Figure 8 is a sectional view taken substantially on line 88 of Figure 2.

Referring to the drawings wherein like numerals designate like parts, it can be seen that numeral 5 generally refers to the chassis or frame of the machine which consists of the side bars 6-'I and the end bars 89. Numeral Ill represents a suitable draft beam. At the forward end of the frame is the ground engaging caster wheel' H, while numerals l2l3 representthe main supporting wheels of the machine, each of which is rotatably mounted on one end of the axle l4. As is shown in Figure 3, each end porthe horizontal shaft N which at one end projects beyond the risers H and is equipped with the pinion 20 meshing with the gear 2 i. This gear 2i on a stub shaft meshes with the gear 22 on the shaft with the pinion 23 which meshes with the drive gear 24 on the axle l4.

The gear 22 in turn meshes with the large gear 25, which in turn meshes with the pinion 26. This pinion 26 is mounted on a stub shaft 2! which projects through the arcuate slots 28 on the riser Il'. This stub shaft 21 also extends through the longitudinal slot 29 in the lower portion of the bell crank 30 which is rockably supported at 31 on the side of the hood 46 and has a rod 32 extending from the upper end thereof to the hand lever 33 on the shaft 34, which hand lever 33 is provided with a rack and detent assembly 35. I

As is. clearly shown in Figures 1 and 2, the wheel I2 carries a cam 36 with which one end of the elongated rocker bar 31' engages. This rocker bar has its fulcrum as at 38 and at its opposite end is provided with a spring pressed pawl 39 engaged with the large ratchet wheel 40 rotatably mounted as at 4| on the frame bar 7.

As is shown in Figure 4, the shaft l9 has a drum 42 carried thereby and from this projects a plurality of radially disposed tines 43. On the shaft 21 which is forwardly located of the shaft I9 is the drum 44 provided with the radially disposed tines 45, this shaft 21 of course extending through the arcuate slot 28 and the slot 29 of the bell crank 36.

Numeral 46 represents a hood extending up? wardly from the rear end of the plow shank 47 and terminating over the rear portion of the drum 42. Numeral 48 represents a gathering her; consisting of the side walls a--a and the back wall b and as is clearly shown in Figure 3, numeral 49 represents a cross rod in this box from which extend tines 50. These tines extend upwardly and in close proximity to the drum 42 so as to collect matter on the drum. These tines 5B in other words guide the peanut vines into the box 48 where they rest upon the grille 5! carried by the rod 49.

This rod 49 is rotatable and projects beyond one of the side walls a where it is equipped with a partial pulley wheel 52 over which the cable 53 extends and is secured at one end to the pulley at one end of the pulley groove. This cable 53 extends over the idler pulley 54, forwardly to engage under the pulley 55. This pulley 55 is also a mutilated pulley, the cable 53 being secured in one end of its groove outlet 56.

A rockable arm 51 mounted on the frame bar 1 has a hook head 59 for engaging a lug 59 on the mutilated pulley 55. The opposite end of this bar 51 is in the path of the pintle 59 projecting laterally from the large ratchet wheel 40.

At the forward end portion of the frame 5 is a transverse shaft 60 provided with a pinion 6| engaging the teeth 62 ofthe rack portion of the shank 41 of the plow 63. This plow shank 41 operates in the guide structure 64. Obviously by operating the hand lever 55, the plow 63 can be elevated or lowered and a rack 59 and detent 61 permits this plow to be held at any desired position with respect to the ground;

The shaft 68 to, which the mutilated gear 55 is secured can be rotated by the hand lever 10, so that by releasing the catch arm 51, the load in the box 48 can be dropped and obviously by pulling back on the hand lever' 10, the pulley 55 will automatically catch with its lug .59 behind the catch arm 51.

When the load is 'to-be automatically dumped, the operator depends upon the cam 35. As the wheel l2 rotates, the cam delivers an upward and downward movement to the rocker arms 31 which in turn moves the ratchet wheel 40 one tooth each rotation of the wheel l2 so that eventually the pin 59 in rocking against the rocker arm 51 of the catch will release the catch from the lug 59 of the pulley 55 so that the pulley will be freed and the weight of the load in the box 48 will permit the grille 5i to drop and release the load on to the ground.

It can be seen, that in operation the plow 53 cuts through' the tap roots of the peanut vines and plows them up for the pick-up drum 4. This drum and tines 45 pick up the peanut vines, lift them into the range of the drum 42 which subsequently elevates the vines to a position where they are taken off by the tines 50 and slide into the box 48. a

The throw of the rocker arm 31 for gauging the number of teeth the ratchet wheel 40 is tobe moved each rotation of the wheels I2 is denoted by numeral 13 and consists of a rockable member provided with teeth 14 of different lengths. This swingable member 13 may be provided with a protuberance on, its inner side ens fleable .into

any one of the recesses 15 for holding the member 13 in any desired position so that the .arm 31 can abut any one of the teeth 15 to regula the throw of the said arm 31.
